Step-by-step explanation:
y + 1 = -(x+5)
y + 1 = -x - 5
y = -x - 6
x + y = -6
--Answer--
It's in the picture, desmos will help for graphing.
Answer:
A = correct equation
x = 60
__+ 65 = 125
x + 65 = 125
60 + 65 = 125
Hope it helps!
-2/3
The gradient of a line is its slope. You can just convert the equation to slope-intercept form (y=mx+b where "m" is the gradient/slope):
3y + 2x = 1
3y = 1 - 2x
y = 1/3 - 2/3x
y = -2/3x + 1/3
So, as we can see, -2/3 is the gradient/slope of the line.
